In the Libyan maneuvers of May 1938, the Italians transported two mixed brigades by air, probably in Ca-133 and S-81 aircraft. During the Albanian campaign of April 1939, Italy relied on converted civil air liners and heavy bombers for the 50 aircraft that were used in carrying 1,100 men 90 miles into the Albanian interior in 4 or 5 hours. Unlike her main Axis partner, Italy did not, so far as known, begin hostilities in World War II with a fleet of aircraft designed specifically for transporting troops.
